Can you actually see the headlight aim/moving right? Then when you center the steering wheel it stays pointed to the right?

If so, then I believe its probably not a bad stepper motor inside the headlight. I'm not sure if the stepper motor controls vertical movement but I know it controls horizontal movement.

Maybe your projector is loose and is not mounted all the way?

There are also headlight aiming adjusting knobs for vertical & horizontal adjustment. Maybe the horizontal is just adjusted out of range?

Yes, I can see the headlight move to the right and then it doesn't re-align

Okay, if this is the case, what happens the next time you get in the X? Does it reset to aiming straight somehow?!

Or are you saying this happened one time (pointing to the right) and now its just stuck pointing to the right (passenger only headlight). So, now its always pointing to the right?

No, it realigns itself each time.
I park in backwards all the time, so I'm facing a wooden gate. Every time I startup, they will auto adjust up-down and be good to go. When I turn right, the headlight will somehow stick to the right.

Forgive me, I'm kinda slow so please put up with my questions.

After it sticks to the right, when/how does it realign then?

twins, you changed the avatar? cool..

do you think it is sticking gears? or AHL is gone AWOL? I would have pulled the module and would have swapped the 2 left terminals for the 2 right terminals, to see if the problem stays with the headlight or moves with the switch...
Chris, are you capable of pin switching? i can provide you with the pinout... only if you are capable, otherwise it would not make sense...

Ok, you have me lost there. What is Pin Switching.

and no, currently I don't have a second pair of eyes/ears to help me out.

the "eye" movement is regulated by dedicated pair of wires coming from control module - one pair is going to the left and the other pair is going to right "eye"... if you switch the pairs, and send "left" signal to the right "eye" and the "right" signal to the left "eye", you can test the system: if the problem moves to the left "eye", it means that the signal is corrupted and module needs to be replaced, if the problem remains with headlight, it means that a known good signal did not rectify the issue of the broken headlight.

this way you know what to repair/replace...

Yup. Missing her but I'll have my boys back soon in my avatar.

You know I'm still confused. Apparently, its fine at startup and only screws up when he turns right. He says it resets sometime between when he turns the X off and when he next turns it on.

I would be curious what results he gets from your changing gears idea. I think its a good one. Basically, we want to see if it will reset itself if you go from D to R and back.

Yea, I tried changing the gears thing. No dice.
The light stayed steady for a split second, then started blinking again.
